🔧 Enhance your tubeless setup with Stan's NoTubes Tubeless Valve Stem - Pair! Review

Going tubeless means you need a good seal to hold all that sealant. A first class rim tape seal is essential, then you want a tubeless valve stem that doesn't leak. Stan is great in that regard - easy install and no confusion. Well, applying sealant can make a mess, but the stem isn't the problem. Don't skimp on take out, you don't want to get stuck on the road.

I use it to replace the original valve stem that came with the Ultegra 6700 tudeless wheelset. The original valve is supplied without a removable valve core. To add sealant, I have to remove the tire every time. After replacing Stan's valve stem, all I have to do is use an injector to inject sealant through the valve. This makes it faster and easier. As long as it doesn't leak and works perfectly with the wheels.

I also have valuables from Cafelatex. The problem with them is that the surface that touches the inside of the rim while the rim is concave. I had to shape the cafelatex with a sharp utility knife to make it fit. Also, never buy cafelatex. When it dries out (which happens when you're in a northern climate and you don't drive them for a few months) the cafelatex comes off and the hard brown stuff sticks to the rim. VERY difficult to take off.

I have mounted them on Shimao Ultegra 6800 tubeless wheels Absolutely no problems so far (3 months ride). They were easy to install and made filling the pipes with sealant a lot easier. I have no idea why Shimano put valve stems in these bikes without removable cores. Shimano leaves a lot to be desired in terms of efficient and logical design, but as long as the market firms can fix their shortcomings, anything will work. Excellent valve stems.

I switched to these from the old valve stems I used to start with. Yes, I used valve stems from old tubes when I went tubeless. I was impatient and it worked before. Stan sealed them, slipped them in with no problem. But like old whistles, the legs have come out over time, just like mine. They are a great substitute and probably should have been used from the start. I like the lock nut that you get on other stems that have a built in flange for the o-ring in the nut. It would be a nice…

Most people take a valve stem on long mountain bike rides, thinking it will bend or clog with sealant if they go tubeless. Of course that can happen, but not as often as cutting or breaking a valve. If you're actively riding on rocky terrain, it's only a matter of time before a valve fails or tears off and needs to be replaced. These valves are versatile and easy to install. In the last year alone they have twice saved me from a long hike.
